Ladies + Gents please help!! My Doblo Cargo M/Jet '08 van has recently displayed the Orange Engine Management Warning light. I had the AA out who read the fault as P0641. They were unable to cancel the fault and their Technical Dept suggested it was the Throttle Potentiometer. I have changed this but the problem still persists, and the Engine (starting at the 2nd attempt each time) idles at about 12-1300 rpm. Usually it idles at 1000. PLEASE HELP ME. I need the van for work and im unable to afford dealer prices.
